Looks like there was some missed versioning increase during devel.
So with kernel >= 4.18 version 1.19 is enough to look like 1.20
However backported 1.19 targets seems to not provide all
the capabilities.
Test has to use PV with suffix pv[0..9] otherwise
it's ignored by test suite filter.
Better fix for VG names to use prefix LVMTEST.
Skip the test for runs without LVM_TEST_DEVDIR != /dev
Always use PREFIX for vg header - all tests must use this prefix,
VGs without are not allowed.
Modify pv_symlink test - as the test was checking unsupportable
combination - since lvm2 commands withing testsuite are only
allowed to manipulate with /dev/mapper/LVMTESTXXXX path -
nothing else allowed and fails on being filtered.
Added comment the 'lvs' already initiates dmeventd
Note: we don't have any query mechanism to check if dmeventd
is already running except access of socket which basically
starts dmeventd if it's not running.
For determinist test results lvm2/dm service shall not be present
and running in the system as it may randomize test results.
In case they are found present, this test ends with warning (not failure).
Some older instancies of 'mdadm' opened legs in RW and
closed and opened again and expected exlusive access.
But here udev rule can be fired - so on these versions
slow down whole mdadm runtime by using strace, to
give system a bit more time to finish udev rule.
Make check_lvmpolld_init_rq_count() more compatible with older gawk,
where some functionality was not working properly.
Also change 'not not' condition.
Just like lvm command ignores 0/xxxx report from judging the status.
Avoid using infinite loop and limit report checking to 100 checks.
If it would need more - something is not right.
Our tests may result in producation of huge set of
invalid links in /dev/disk directory depeding on version
of udev and various kinds of failures.
Also we happen to invoke some on-system pvscans generating
local /etc/lvm/archive & backups - remove them when
test is finished.
Try to synchronize with colliding udev.
Also retry once if there is some failure with some
sleep between next retry.
Use oflag=direct for wipping without wipefs.
Combination of throttling and slowed device is a bit faster.
Also add FIXME about the mutliple spawn polling processing
when activating invidual LV for a pvmove.
Use for testing new mdadm_create aux wrapper.
Place functionality into a 2 pass loop - one for 'auto' other for 'start'.
Share same tests between raid level 0 and level 1 version of raid.
Add generic wrapper for mdadm --create which takes
normal 'mdadm' args - but allows us to handle differences of
mdadm usage across various version of mdadm tool.
Resulting MD device is availalble in $(< MD_DEV).
Automatic cleaning is made through cleanup_md_dev
Calling of mdadm_create cleans previous MD dev if it exists.
When testing installed binaries on system, use more 'built-in'
predefined settings to usethem with their compiled-in values.
Also it's better to use same locking dir so the system's pvscan
is not unexpectedly interferring with test commands.
We have here some kind of catch-22 - since older kernels do
use 'resync' while new 'recover' for initial raid synchronization.
So now - how do we recognize in which state of raid we are.
ATM seems to be simplest to simply keep disabled droping of primary raid
leg unless we are in sync.
FIXME: we should add a target version check and enable removal
Always shift created virtual PVs on backing device by 1MiB
and leave 1MiB free space at the end of device.
This way the system doesn't see same PV headers at multiple devices.
Adding full filesystem sync, trying to fight with strange error from losetup:
losetup: loopa: failed to set up loop device: Resource temporarily unavailable
loop0: detected capacity change from 0 to 4096
loop_set_block_size: loop0 () has still dirty pages (nrpages=13)
Also reuse internal aux wipefs_a
This modification supports dynamically obtaining the value of PAGE_SIZE,
which is compatible with systems with PAGE_SIZE of (4K/64K)

This reverts commit 99b6173f10.
These tests are disabled with lvmlockd because they use
snapshots without an origin which is not permitted in a
shared vg.
user creates a file listing real devices they want
lvm tests to use, and sets LVM_TEST_DEVICE_LIST.
lvm tests can use these with prepare_real_devs
and get_real_devs.
Other aux functions do not work with these devs.
To better test actually fsadm in test suite - avoid setting
LVM_BINARY locally - since test setup already modifies
PATH to find test's lvm binary as the 1st. in path.
